-All the particles of a pure substance are alike, no matter where the substance is found 
-Elements helium and krypton are both colorless, odorless, unreative gases.
-These elements have different densities. ]]> 2016-11-04 20:58:28 UTC https://padlet.com/334747/36rchtumuogk/wish/135510968 334747 https://padlet.com/334747/36rchtumuogk/wish/135511906 -Different reactions involve changing compounds into other compounds.
-All cases through different materials exist after the reaction occurs. 
-Chemical properties include changes that occur when compounds are exposed to other chemicals or to heat or light. 
-Properties of a compound differ, not only from those of other compounds, but also from those of it's elements. 
-Carbon monoxide has one carbon atom combined with one oxygen atom. 
-Properties of a compound depend on which elements combine and how much of each element is in the compound. ]]> 2016-11-04 21:08:21 UTC https://padlet.com/334747/36rchtumuogk/wish/135511906 334747 https://padlet.com/334747/36rchtumuogk/wish/135512468 -Chemicals can form mixtures, that means that each chemical keeps it's same density. 
-Different mixtures are not separated so easily, salt can't be simply be picked out of seawater. 
-Another method of separating the parts of a mixture is to dissolve one of the substances in water, filter the mixture, and then evaporate the water after you finish filtering the water.  
-Water is the solvent of many solutions that come across you daily bases. 
- Your body contains many water solutions such as blood plasma, saliva, and tears.]]> 2016-11-04 21:13:32 UTC https://padlet.com/334747/36rchtumuogk/wish/135512468
